My daughter is in the process of buying a new property that has a tree planted tight against it. The Surveyor said that the tree could cause problems in the future and that it is already interfering with the down pipe and front upstairs bedroom window. The developers say it is part of the tree planting scheme submitted when planning permission was applied for and say it will cause no harm and should stay. My question is if the sale goes ahead and my daughter becomes the owner of the tree can she remove it?

Depends on the wording of the condition. It is likely to state that if it is removed within 5 years it must be replaced or something similar. You can submit amended soft landscape plans and see what they say.

The reality is your daughter can remove/transplant the tree as soon as she owns the land. The builder has to plant as per the landscaping outlined in their planning application. As the new owner she can remove the tree.
